Sweet potato recipe from Daisy Mae's Barbecue on 11th Avenue?

This is hands down the best sweet potato recipe I have ever had. We served them to friends on Saturday, and I've never heard such raves in my life. I believe there is banana in the recipe. There may also be pineapple. Is it possible to get the recipe? The address for Daisy May's BBQ is 623 11th Avenue in Manhattan.
